Abstract:: In order to study the numeric character and spatial pattern of Robinia pseudoacacia L. under two kinds of recovery modes, SⅢ and the SⅤ plots after 17 years of reclaiming were choosed as study area. The size-class distributionm, the shoot blight individuals of Robinia pseudoacacia L. distribution and the character of invader species were comparied. The results were obtained as following: (1) the survival rate and the number of alive Robinia pseudoacacia L. individuals at the configuration mode of locust+elm+ ailanthus were higher than the configuration mode of Locust pure forest; (2) due to the existence of the relationship between competition and some environmental factors such as water, the space distribution of Robinia pseudoacacia L. in different diameter classes at SⅢ and SⅤ plots showed different spatial heterogeneity; (3) the shoot blight was related to the plant density and position of Robinia pseudoacacia L., and the shoot blight in SⅤ plot was obviously more serious than that in SⅢ plot, because of the wind.
